2 erases in the arrangement shown in Fig. i the motor g is provided with 'e shunt-field g and wires f and g are nrovided with a switch 9 which when closed is adapted to complete a circuit through the Wires f and g, motor g and the resistance-coils and contests hereinlbefore mentioned.

In the arrangement shown in Fig. 4 the electromagnet c is iii electricsl'communicetion with the Wire 9' by means of the conductor h, and said electroinsgnet or solenoid c is also in direct electrical communication with the circuit-breaker d, and by means of 2. conductor h is in communication with the solenr5 oid 0 which is else in communication with the circuit-breaker 01 end with a. solenoid by means of a. conductor it and the solenoid c is in electrical communication with the circuit orcsirer d and with solenoid c, which in turn is in electricel communication with e.

conductor at, which connects the circuitbreelierd or one oi the members thereof with -the wire g. it will therefore be seen that fires the switch g" is ciosed s circuit is formed 2 5 through the wire f, the resistances e e, 61:43., the contacts 6 e 850., the conductors g and d circuit-breskers d F, and d, solenoid c, conductor h, and wire g, and the solenold 6 .Jeing thereby energized attracts the 7,0 arm 1'? and draws the some into the vertical position indicated in dotted lines in Fig. 2.

When the arm 5 is drawn into its vertical position, the upper end thereof bears against the contact e, and the log or projection b oi ;5 the arm 5 opens the circuit-browser d, and s circuit is tlnis closed through the m sin Wires f, arm T3 contact c, 'esistsnce-coils e, 6 and c main. Wire g motor g and the resistence-coil e is thereby cut out and the motor 40 g is ener zed and :1. Supplemental circuit is formed t iron h the conductor (Z circuit breakers d son (1 solenoids c and c, and conductor h to the Wire 9, and the solenoid c is ener izecl, thereby attracting the arm is, 5 whicii when in its vertical position cuts out the resistance-coil 2 and. opens the circuitbresker (P, and this places the solenoid c in the supplemental circuit cause of the fact that the circuit-breaker d had been ope When the solenoid c isenergized, the arm .1) is attracted thereby, and when in its vertical position. the resistance-coil e is cutout end the circuit-breaker d is opened, and the 5 5 solenoid c is thus made a. part of the supplemental circuit referred to, end the arm 5 is thereby moved to its vertical position and the resistance-coil e thereby cut out, and a insin circuit formed through the wire f, are} b contact 8, wire g, and motor 9 and the motor g is receiving the highest possible potcntieLe-nd at tiresome time s lementsl circuit is formed. through the so onoids and the resistance-coils wl'iicli is ewer- '55 iul enough to hold the suns if if, can, in

just described bev their vertical positions as long as the switch g is in its closed position, and it is for this reason that the arrangement just described is adapted for use in elevators and the like where but a short period of operation of the motor 9 is desired because of the fact of the considerable loss of electrical energy necessary to maintain the arms in their vertical positions. I

the arrangement shown in Fig. 5 of the drawings is essentially similar to that shown in-Fig. 42 with the exception that connected with the shunt-field g is a conductor i, which forms a supylemental Winding of each of the solenoids or electromagnets c &c., and in this arrangement 1 also rovide on additional circuit-breaker d, wliic is connected in the some manner as the cil'cnit breekers hereinbefore mentioned. The operation during the early stages oi this arrangement 18 orecisely the some as that described in Fig. 4, out with this diiierence,tl1et when the stint is sttmcted to its vertical position the supplemental circuit-breskerd is open, thereby cutting out sli oi the solenoids as well as all oi the resistance-coils and. e small amount of electrical energy passes through the shuntfield and the supplemental windings of the solenoids, this amount of energy being just SHillGlG/Htto hold the arms in their vertical positions, and it will be seen that this s:- rengement is adapted for use in connection with continuously-operated machinery or the like, because of the fact that it very small amount of electrical energy is necessary to retain the carts in their operative or closed positions.

In Fig. 6 oi the drswings l have shown the apparatus adopted for use in connection with illuminated signs, four letters of said sign being sliownnsmcly, A B C D-wl1icli are connected with the main wire f and with the corresponding contacts 2, c e snd e end in this arrangement I employ a number of circuit-breel rers equaling the num ber of arms, and when tire switch 9" is closed a circuit is formed through the Wire f, circuit-breakers cl, d (i and d, solenoid c, and wire g, end the solenoid 0 being energized attracts the arm 5 and a circuit is then formed through the arm I), contact a, letter A, and WiIGSfZLZlLl g and this operation of the arm 5 operating tire circuit-breek r d, throws the solenoid into notion, which, attracting the arm-b places the letter B in electrical connnuniceo therein, and the arm b, opening the circuit-bresker (Z oper stes the arm b", thereby illuminstin the letter C, end as the circuit-breaker d .lfiS been 0 ened by the arm I) the solenoid c is t rown into action, which attracts the arm 7 and the circuit is then closed through the letter B, which is illuminated, but only for e. brie-i interval, for the reason that the circuitlireelrer :1, being open, brooks the main cirtion and cnergi the lifilits cuit and all of the arms return to their normal positions, and when the circuit-breaker d" returns to its normal position the operation just described with reference to all of the letters A, B, C, and D is re eated, and it will therefore be seen that the etters are illuminated consecutively for but a brief period of time and the flashing effect desired in illuminated si ns is obtained.

It will therefore be seen that my invention consists of "magnetically-operated arms, adapted to cut out a plurality of resistancecoils consecutively or to illuminate a plurality of characters consecutively and for brief periods of time, and although I have shown my solenoids connected with both sides of the armature-circuit it will be understood that they may in some cases be connected direct with the line independent of the armature-circuit, and various changes in and modifications of the mechanical arrangement shown and described, as well as of the electrical arrangement, may be made without departing from the spirit of my invention or sacrificing its advantages.

The controlling devices for the electricsign displays herein described are not claimed in this case, but are made the subject of a divisional application filed February 14, 1906, Serial No. 301,034, and the circuitthrough said circuit-breakers, a supplemen- -tal winding for said electromagnets arra ed to be operated by the corresponding one of. said electromagnets through the main winding thereof and be held in the last-named position through the supplemental winding thereof, substantially as shown and described.
